<p>PROBLEM TO BE SOLVED: To obtain an FRP plate which is little in disorder of fiber orientation in forming, little is warp and distortion irrespective of being thin, and excellent in physical properties by a method wherein a continuous fiber layer which contains properly arranged continuous fiber and of which a thickness is specified is provided, and a nonwoven layer is arranged on both sides. SOLUTION: A lamellar structure of a properly arranged fiber layer and a nonwoven layer is provided. A continuous fiber layer wherein its thickness after molding is within a range of 0.3-0.5mm, is provided, and the nonwoven layer is provided on its both sides. A unidirectional prepreg 2 is laid on the nonwoven 1 so that a direction of the continuous fiber to a standard axis 10 becomes a 0 deg. direction. Further, after laying a unidirectional prepreg 3 on the unidirectional prepreg 2 so as to become 90 deg. to the standard axis 10, air between the prepregs 2 and 3 is squeezed out with a roller like rotary material. Then, a nonwoven 4 is laid, which is pressed with the roller in the same way. After laying the prepregs 5, 6 in the same way, a nonwoven 7 is laid on the outermost layer.</p> |
